I'd definitely wait as it will make your new phone all the more different / exciting. I would wait but the X is a bit further away and I may well need to update when my s3 Watch arrives if not for app updates in the meantime.
I'm definitely waiting until I get my 8 Plus before using iOS 11 - not gonna update my 7!!
Say what? Seriously! What about the 'only £10 more a month for the X'? You are not going to end up as indecisive and cutiekitty last year? The saga ;-)
....yea, I know - I am SO indecisive!!!
Well, I know I said it's only another £10 for the X but I wasn't really taking into account the cost of the 8 Plus as well! The 8 Plus is less than a tenner extra a month than what i am currently paying for the 7 but the X will be 'just another tenner' on top of that !!! So i'd be looking at around £40 odd for the iPhone X and £30 ish for my monthly EE sim only deal - not sure I am happy to pay around £70 a month for phone & contract + I'm not totally sold on the 'no home button' thing of the X!!!
What is your deadline for sending your handset to Envirofone? Have you taken up their usual 7 extension offer? If they still do that - they did last year. If you have time you could always get the 8+ on IUP and try for a few days to see if you like the size etc.
I received an email from them, on 17th Sept stating that I hadn't yet sent in my iPhone 7 to them and that my price was locked in for 14 days. My original confirm email from them was on 12th Sep, so I guess I will essentially have had 3 weeks worth of that locked in price!!
